If your device has a single RAM region, you can split it into 2 parts by editing the MEMORY part of the linker script to try out the techniques from the rest of the tutorial. Remove the “.newsection” reference from.isr_vectorand place it into a separate section at the end of the ...
Basic linker script SECTIONS { ❶ . = 0x00000000; ❷ .text : { ❸ abc.o (.text); def.o (.text); } ❹ } ❶ SECTIONS命令是最重要的链接器命令,它指定了如何合并这些段以及将它们放置在什么位置。 ❷ 在SECTIONS命令之后的语句块,.(dot)表示位置计数器。位置总是初始化为0x00000000。
